The Lehmann Black Cube—a classic among phono preamps, famous worldwide for its sweet and punchy sound with MM or MC pickups.
This one enhanced with the extra potent PWX Power Supply.

Suitable for MM (~3.5mV) pickups and moderate output MC (~.35mV).
Gain is reported to be 46dB MM and 66dB MC.
Resistive Cartridge loading: MM 47K, MC 83, 100, 470 ohms.
(Will be shipped set for MC at 100 ohms.)

With its 46 to 66 dB (2000x) of gain, virtually all common systems from high-output MM to MC may be connected to the Black Cube SE.  

The high-precision passive RIAA filter network sits between two linear gain stages and has utilizes high-grade, surge-proof and narrow tolerance polypropylene foil capacitors for lowest noise.

The potent external PWX power supply is compact in size too and separated from the preamp, so the Black Cube SE may be placed right next to your turntable, minimizing losses due to cable lengths.
